Portelligent and Semiconductor Insights published a document describing interals of IPhone 3G. Techonline described the details. (Previous IPhone 3G internals photos can be viewed here)

Commuunications (3G/GSM) are on Infineon chips. One for GSM/GPRS/EDGE, another for WCDMA/HSDPA (3G). GPS module is not SiRF as we all thought. Apple uses PMB 2525 Hammerhead II. The Hammerhead II integrates an assisted-GPS (A-GPS) baseband processor with a low-noise GPS RF front end and multi-path mitigation to avoid large errors in urban environments.

DevTeam recently published a video of working PwnageTool 2.0 - for unlocking, activating and jailbreaking IPhne fimware, that will work with the new firmware 2.0.

"Many many hours have gone into this and now it should be as easy enough for your grandmother to use. We’ve added lots of new features, including 2.0 support, spotlight file indexing of .ipsws, canned websearches, installer custom configuration, custom root partitions and various other things that you’ll see on the release. Release date is soon although not this weekend. So check out the video, hopefully it will hold you off until we release."

PwnageTool works with 2.0 upgraded 1st gen (!) iPhones if they are activated or not.

During Java instalation there was sample programm installed. It is called HelloJava. It is a bit more complicated than basic console HelloWorld-type application, that we tried to compile and run during this tutorial. HelloJava uses gui and SQLite. It uses several classes, that are bridges to IPhone's functionality (GUI, sound, SQL, etc). But all that it does is it reads contacts' first and last names from IPhone's database (throught SQL select statement) and shows them on the screen in GUI mode. It also produses simple sound in the end.

First of all I'd like to say we all want to use legal IPhones and operators. So everything written below is for testing purposes only . Hopefully this technology will be avaliable on all IPhones sold worldwide. You also might need to recover your IPhone, so make sure you backed up all your data. I personally did everything without any problems and needs to recover. Everything you do is your responsibility, etc...

So let's start, because it's worth it! It's just one evening and you will be able to create your personal Java application, compile and run it on the IPhone, and amaze all your friends .

There are two ways to enable Java applications run on the IPhone. The first one is to port Java to IPhone, and this is preferrable The second way is to create automatic Java to IPhone porting solution for individual applications.

A company called Innaworks announced an interesting product called alcheMo. alcheMo is an automated system to port J2ME application to a native platform such as BREW and IPhone.

alcheMo technology is basically J2ME to C++ translator and the run-time library. It converts Java application to C++ application, which can be compiled, run and debugged. Using native run-time libraries the native executable is created. The alcheMo run-time library provides equivalent functionality to those associated with J2ME, including support for automatic garbage collection, multi-threading and extensive subsets of CLDC 1.1 and MIDP 2.0, and extension JSRs.

There are several examples of porting games to BREW platform. Hopefully there will be some for the IPhone in the near future. For now alcheMo is in beta state, potential developers are invited to join.

By the way, alcheMo for iPhone supports the accelerometer, the touch screen and other unique iPhone features, through standard MIDP 2.0 API, JSR-256, and, where necessary, extension APIs. If J2ME application uses such APIs, it will automatically and immediately be accelerometer or touch screen capable on iPhone.
